I love pumpkin pie! This recipe is easy to make and it's a great way to use up your Oreo cookies. The Cool Whip makes it extra creamy which I love. The sherbet also adds a nice flavor to the pie, but you can always add any other flavor that you want. This recipe can be easily doubled or tripled if you need more pumpkin pie. My family and friends love this pie! If you're not into Oreo cookies, you could substitute any cookie of your choice.
